Patented Sept.. 11, 191'?.

Application led December 11, 1915. Serial No. 66,310.

To all whom t may concern.' s

Be it known that I, 'HENRY T. ATKINSON,

Va citizen of the United States, residing in of the window casings with respect to the sash mounted therein.

In this specification and the annexed drawings, I illustrate the invention in the form that I consider the best, but it is to be understood that I do not limit myself to such form because the said invention may be embodied in other forms, and it is also to be understood that in and by the claims following the description herein, I desire 4to cover the invention in whatever form it may be embodied.

Referring to the two sheets of drawings:

Figure 1 is a front elevation of a window constructed in accordance with this inven-Y tion, showing the sash in the closed and locked position.

Fig. 2 is a vertical cross section of the same, taken on the line II-IL showing the sash in the advanced position within the vestibule casing. i

Fig. 3 is a plan view from the top with the lintel removed showing the sides of the frame in cross section.

Fig. 4 is a detail in end elevation of the supporting hardware, including the sash support and the runway therefor.

Fig. 5 isa longitudinal cross section of the same on the line V-V, the sash support being omitted.

Fig. 6 is a plan view of the lock plate attached to the stool of the window casing.

In detail the construction illustrated in the drawings includes the vestibule window frame, comprising the stool 1 at the bottom, the top plate 2, and the side frames 3 and 4. Within the vestibule frame is the window frame composed of the bottom rail 5, the

Vlintel 6 and the side stiles 7 and 8, framing the window opening. To this assembly is added the sill 9, the usual exterior trim 10 frame composed of the bottom rail 13. the

top rail 14;, and the side Stiles l5 and 16,

glazed in the usual manner. This sash frame snugly tits the window openings within the window frame. The top and the two sides of the window opening are slightly tapered, to fit a similar taper on the top and sides of the sash, to insure good weathertight engagement between the sash and the window frame, that may also be provided with any suitable form of weather strips. The bottom rail of the sash frame is rabbeted at 17 to rest upon the rabbeted bottom rail 5 of the window frame, provided with a longitudinal groove 18 having the holes 19 leading therefrom at intervals, to drain oil any water that may run down the outside of the sash and collect within the groove 18. The exterior trims 10 and l1 slightly overhang the margin of the window opening to act as a stop as at 20, for the sash frame.

The sash guides 21 and 22 are fixed to the underside` of the top plate 2 on opposite sides of the center, parallel with the sides 3 and 5L of the vestibule frame. These guides preferably consist of the -plate 23, having the overhanging margin 24 to receive the screws 25 that screw into the top plate 2. These plates 23 are provided with a pair of downwardly extending opposed flanges 2G and 27, forming longitudinal channels`28 with the central openings or-slots 29 between the edges of the flanges. The sash is hung on the supports 30 secured to the sash by the screws 31 in alinement with the slots 29 in the said guides. The supports 30 slide freely within the slots 29, the sash being supported by the hemispherical heads 32 slidable within the channels 28 and engaging the lugs 26 and 27. The frame thus supported slides freely from the window opening 4out into the vestibule frame. In the advanced position, the heads 32 engage the pockets 33 formed in the opposite lugs 26 and 27. The heads 32 descending therein are held by the weight of the sash in that position. The bottom rail 13 of the sash is provided with the bolts 34 and 35 slidable within the brackets 36 and 37 respectively, the bolt being forced down by the eXpansion of the springs 38 confined within said brackets,

When the sash is in the closed position within the window frame, the bolts 3i and 35 engage the holes 39 in their respective plates 40, fixed to the stool 1 beneath the bolts, the plates 40 are provided with a transverse slotfsl, beginning in alinement with the hole 39 and extending inwardly to Ward the center of the stool. When it is desired to move the sash into the advanced position shown in Fig. 2, the bolts 34 and 35 are raised by their convenient handles and permitted to. slide along the plates 40, until they drop intothe slot il under tension of the springs 38. rllhe sash hanging suspended in perpendicular alineinent with the plane or` the Window opening is held at the top by the engagement of the head 32 in the sockets 33 and at the bottom by the bolts 34 and 35. Means may be provided for locking the bolts 34 and Sby a removable key or other precautionary measure, to prevent burglarious entrance through the WindenT or tampering therewith.

liritlitlie sash in the position indicated in Figs, 2 and 3 a margin of space between the interior surface of the vestibule trame and tlieedgesioi' the sash permits a large `volume of air to enter through the vestibule, without.creating.disagreeable drafts or undesirable air currents. rllhe force of the wind, if'any, is broken by the glass X in the sash :trame and is directed laterally thereby and caused toenter through the vestibule with the force :thereof so diminished as not to be disagreeable. rlhe window beingopened -alt the top as well as at the bottomv and sides, perfect circulation oi the air within the room is assured, Without the disturbance of the draperies, if any, ornamenting the window-frame. In addition to preventing drafts and'disagreeable air currents, soot and dirt are excluded from entrance through the Window to a very great extent, making it possible to ventilate through the nf'indow in the face of a strong Wind, or even during a rain storm, Without any disagreeable coiisequences, unless the rain was beating directlyV against the glass.

tion.

- i lf it is desired to open the WindenT en tirely, the bolt 34C is raised out of engagement with the slot al, and the sash tilted latorally until it unseats the head 32 from the socket 33 on that side of the window sash, bringing the head into coincidence or registry with the. opening a2, permitting the eiitire disengagement oft the support 30 from ,the guide, the length oit the slot al on the opposite side, permitting the bolt 35 to swing inward toward the center ot the stool Without disengaging from the plate -l0, and permitting the sash to pivot on the support 30 and the bolt 35, so that the sash may be the building to Wash the outside of the glass. i

and lock thesash 'at the bottom.

These are only av r-feiv of the many advantages of this inven- The same operation with respect to the supportsand the bolts on the opposite sides oi the sash )ermit the sash to swine` in the op- Aposite direction in an obvious manner.

l/lhen the sash is in the closed position, as illustrated in Fig. l, the bolts and 35 engage their respective holes 3Q in the plates 40 The pivoted catches -flll and la pivot-ed on opposite sides of the sash, engage the-slots iorn'ied f' in the plates L6 ixcd to theside stiles 7 and S of the window `i"iaiile,- to `securely loclrtlie sash iif'ithni-the window opening. The sash may be readily removed-fronithe Window iframe-by releasing all ci the various Vbolts and catches and hitting the heads out ot engagement with the Vguidessecured tothe top plate 2 which will entirely free the sash v 'troni engagement with the frame. i f
